Hawker Hurricane IIA Z2389

In late 2011 Broadway Electrical were contacted by Brooklands Museum in Weybridge with regards to the Hurricane aircraft they were restoring, and were enquiring about the overhaul of the Rolls-Royce Merlin engine's starter and generator (dynamo)

The aircraft was a HAWKER HURRICANE IIA Z2389 which joined 767 Regiment of the Red Air Force on the Kola Peninsula. On the 20th June 1942, it engaged two Messerschmitt Bf 109Fs and five Bf 110s over remote part of Murmansk, but was shot down along with two other Hurricanes. Z2389's pilot Ivan Kalashnikov survived the forced landing.

The Museum later explained that fifty years later, Z2389 was found by Russian historians and its remains were taken to St Petersburg in 1996, in 1997 the part restored aircraft was first seen by a WW2 recovery specialist, Jim Pearce, then inspected by Brooklands Museum. The Hurricane arrived at Brooklands on the 14th October 1997 and was the first historic aircraft in Britain to be purchased with Heritage Lottery Fund grant, and it's restoration began in 1999.

The engine which the museum is using is a Rolls-Royce Merlin III. Built at Derby in 1938 with s/n 2401/A118376, this rare early example of a Merlin engine was stored by the RAF until sent to Canada in 1941 for potential use in a Hawker Hurricane or a Fairey Battle. Preserved post war in Canada and then sent to the USA, it returned to the UK in 1988 and was bought by the present owner Mike Lodge in 1998. Offered on loan to Brooklands Museum's Hurricane project a few years later, after several independent expert inspections, it was returned to Rolls-Royce at Derby where Rolls-Royce Heritage Trust volunteers made a thorough examination of its condition from 2007 - 2010 before it returned to Brooklands.

Brooklands Museum contacted us after seeing a write up about our workshop in "Classic Motors Monthly" by Michael Ware, the former curator of Beaulieu Motor Museum, The challenge being the 12V starter and 24V dynamo of the Merlin engine. The challenge was accepted and both units were brought back to the workshop in non-serviceable condition. Both units were put on the test bench to see where the faults may lie before being dismantled and assessed. One main issue was the voltage difference of both units. The most cost effective way to resolve this for the museum was not to rewind the dynamo to 12V but to put in a split charge/start system. So with this agreement, the dynamo was rebuilt to it's 24V spec, with a wiring harness and external regulator supplied. The starter had a broken top/front plate which was replaced and its armature rewound to 12V spec.

Both units were rebuilt to the high standard that Brooklands required, retested again to make sure they were running correctly and smoothly, before having their final clean and inspection.

They were delivered back to the museum and on several occasions we revisited Brooklands to advise with the fitting and wiring of the units onto the aircraft.

We would like to wish Brooklands Museum every success in completing their restoration.
